Application filed November 10, 1915.

To all whom it may concern:

Be it known that I, THOMAS Knnrrnn, a citizen of the United States, residing in the city and county of Philadelphia, State of Pennsylvania, have inventeda new and useful Hat-Pin, of which the following is a specification.

2 represents a side elevation of the tightening member employed. Fig. 3 represents a longitudinal section of the bushing employed. Fig. 4 represents an end view of the tightening member. Fig. 5 represents a side elevation of the handle of the device with a ferrule member thereon.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designate the handle of the device, the same having a longitudinally-extending bore 2 therein to receive one end of the pin proper 3, said end having a head 4 thereon which acts as a stop to prevent improper disconnection of said pin from said handle, as will be hereinafter referred to. On the end of the handle 1 in the present case, the left hand end, is the ferrule 5 which is formed with a shoulder 6 which is adapted to abut against said end of the handle as a stop. Continuous of said ferrule from said shoulder 6 is the bushing 7, whose interior is a smooth conical surface 8, and whose exterior occupies the recess 9 in the handle 1, said recess being in communication with the bore of said handle. Interposed between the exterior of said bushing 7 and the wall of the recess 9 is a mass of material such as shellac, whereby said bushing and the ferrule 5 are firmly cemented in the handle, and the ferrule held tight against the end of said handle, said wall and the exterior of the bushing being slightly roughened, whereby the shellac or cement will take firm hold of the same for i Specification of Letters Patent.

evident purposes. The interior of the forrule is cylindrical and screw threaded as at 10, the threads extending to or toward the wide end of the conical surface 8 of the interior of the bushing 7 11 designates a sleeve having a bore 12 therethrough for the passage of the relative portion of the pin 3, the latter being movable in said bore, so that the pin may be lengthened and shortened outside of said sleeve, while the head end of the pin is mov able in the handle 1, according to the movement of the portion of the pin outside of the sleeve, it being noticed that the exterior of the body of the latter is cylindrical and screw-threaded as at 13, and has a nose 1%, the exterior of which is a plain conical surtudinal division or split 16 forming jaws 17 which are somewhat elastic and which may be compressed or contracted toward each other, and afterward expanded and so caused to resume their normal position, it being evident that the bore 12 of the body of the sleeve extends through the divided jaws 17, so that the pin proper will occupy the interior of said jaws, it being noticed that the body of the sleeve is provided with a. milled rim 18 for conveniently rotating the sleeve, it being adapted also as a shoulder to abut and tighten against the ferrule 5 when the pin has been adjusted and clamped in position, it being noticed also that said rim 18 is of greater diameter than the body of the sleeve, so that it forms a convenient member to be grasped by the fingers for rotating the sleeve.

The operation is as follows: The sleeve is rotated so as to be somewhat loosened when the pin may be moved in and out of the same to the extent required. Then the sleeve is rotated in the reverse direction when it screws into the ferrule 5 and its nose 1 1 enters the conical part 8 of the bushing 7, whereby said nose has its jaws contracted, and so the walls of the bores of said jaws close tightly against the pin and clamp the same preventing it from movement or change in its adjustment. When the sleeve is loosened or screwed out the nose 14 leaves the conical bushing and the jaws 17 are released of the latter, whereby they expand and lose their holding power on the pin, and thus the latter may be moved in or out from further adjustment, but the head 4 may abut against the inner ends of the jaws of the face as at 15, said nose having in it a longi' nose thus preventing the improper disconnection of the pin from the handle and vice versa.

It is evident that the sleeve 11 with its nose 14 thereof acts as a clutch whereby said nose in the screwing-in action of the clutch may be contracted by the inner wall of the bushing 7, and so close tightly on the portion of the pin within said chuck while the rim 18 in the home-position of the chuck may be tightened against the edge of the ferrule so as to prevent improper reverse turning, and consequent unscrewing of the clutch and release of the pin.

Having thus described my invention what I claim as new and desire to secure by Letters Patent, is

1.. In a hat pin, a handle having therein a bore, a hollow ferrule formed of a bushing adapted to be connected rigidly with the handle in the outer end portion of said bore, the inner wall of said ferrule being respectively conical on its inner end portion, and screw-threaded on its outer end portion a sleeve having a bore therein, a hat pin proper adapted to occupy slidingly said bore, the exterior of the outer portion of said sleeve being screw-threaded, and a nose on the inner end portion of said sleeve toward the handle of the device, said nose being longitudinally divided forming resilient jaws and being exteriorly conical, and a grasping rim on the outer end of said sleeve. A hat pin, a handle having therein a bore, a hollow ferrule formed of a bushing adapted to be connected rigidly with said bore in the outer end portion thereof, the inner wall of said ferrule being respectively conical on its inner end portion, and screwthreaded on its outer end portion, the exterior of said bushing intermediate of its ends being provided with a shoulder which is adapted to abut the adjacent edge of said handle, and a sleeve insertible in said ferrule and having therein a bore, a hat pin proper adapted to occupy slidingly said bore, the exterior of the outer portion of said sleeve being screw-threaded, a nose on the inner end portion of said sleeve toward said handle, said nose being longitudinally divided forming resilient jaws and being exteriorly conical, and a shouldered rim on the outer end of said sleeve, said rim being adapted to abut the adjacent edge of said ferrule.

3. A hat pin, a handle having therein a bore, a hollow ferrule formed of a bushing adapted to be connected rigidly with said bore in the outer end portion thereof, the inner wall of said ferrule being respectively conical on its inner end portion, and screwthreaded on its outer end portion, the exterior of said bushing intermediate of its ends being provided with a shoulder which is adapted to abut the adjacent edge of said handle, and a sleeve insertible in said for rule, and having therein a bore, a hat pin proper adapted to occupy slidingly said bore, the exterior of the outer portion of said sleeve being screw-threaded, a nose on the inner end portion of said sleeve toward said handle, said nose being longitudinally divided forming resilent jaws and being 6X- teriorly conical, and a shouldered rim on the outer end of said sleeve, said rim being adapted to abut the adjacent edge of said ferrule, the end of the pin in the bore of the handle having thereon a head adapted to abut the inner end of said sleeve as a stop against outer displacement of said pin proper.
